		<p>Any field that can receive input can be converted into an Autocomplete, namely, <code>&lt;input&gt;</code> elements, <code>&lt;textarea&gt;</code> elements, and elements with the <code>contenteditable</code> attribute.</p>

		<p>By giving an Autocomplete field focus or entering something into it, the plugin starts searching for entries that match and displays a list of values to choose from. By entering more characters, the user can filter down the list to better matches.</p>

		<p>This can be used to choose previously selected values, such as entering tags for articles or entering email addresses from an address book. Autocomplete can also be used to populate associated information, such as entering a city name and getting the zip code.</p>

		<p>You can pull data in from a local or remote source: Local is good for small data sets, e.g., an address book with 50 entries; remote is necessary for big data sets, such as a database with hundreds or millions of entries to select from. To find out more about customizing the data source, see the documentation for the <a href="#option-source"><code>source</code></a> option.</p>

		<h3>Keyboard interaction</h3>

		<p>When the menu is open, the following key commands are available:</p>
		<ul>
			<li>UP - Move focus to the previous item. If on first item, move focus to the input. If on the input, move focus to last item.</li>
			<li>DOWN - Move focus to the next item. If on last item, move focus to the input. If on the input, move focus to the first item.</li>
			<li>ESCAPE - Close the menu.</li>
			<li>ENTER - Select the currently focused item and close the menu.</li>
			<li>TAB - Select the currently focused item, close the menu, and move focus to the next focusable element.</li>
			<li>PAGE UP/DOWN - Scroll through a page of items (based on height of menu). <em>It's generally a bad idea to display so many items that users need to page.</em>.</li>
		</ul>

		<p>When the menu is closed, the following key commands are available:</p>
		<ul>
			<li>UP/DOWN - Open the menu, if the <a href="#option-minLength"><code>minLength</code></a> has been met.</li>
		</ul>

		<div>
	<h3 id="theming">Theming</h3>

	<p>The autocomplete widget uses the <a href="/theming/css-framework/">jQuery UI CSS framework</a> to style its look and feel. If autocomplete specific styling is needed, the following CSS class names can be used:</p>
</div>

		<ul>
			<li>
<code>ui-autocomplete</code>: The <a href="/menu/#theming">menu</a> used to display matches to the user.</li>
			<li>
<code>ui-autocomplete-input</code>: The input element that the Autocomplete widget was instantiated with.</li>
		</ul>

		<h3>Dependencies</h3>
		<ul>
			<li><a href="/category/ui-core/">UI Core</a></li>
			<li><a href="/jQuery.widget/">Widget Factory</a></li>
			<li><a href="/position/">Position</a></li>
			<li><a href="/menu/">Menu</a></li>
		</ul>
	</div>
<h3>Additional Notes:</h3>
<div class="longdesc"><ul>
<li>
			This widget requires some functional CSS, otherwise it won't work. If you build a custom theme, use the widget's specific CSS file as a starting point.
		</li>
<li>
			This widget manipulates its element's value programmatically, therefore a native <code>change</code> event may not be fired when the element's value changes.
		</li>

<div class="default">
<strong>Default: </strong><code>none; must be specified</code>
</div>
<div>
				Defines the data to use, must be specified.
				<p>Independent of the variant you use, the label is always treated as text. If you want the label to be treated as html you can use <a href="https://github.com/scottgonzalez/jquery-ui-extensions/blob/master/src/autocomplete/jquery.ui.autocomplete.html.js">Scott González' html extension</a>. The demos all focus on different variations of the <code>source</code> option - look for one that matches your use case, and check out the code.</p>
			</div>
<strong>Multiple types supported:</strong><ul>
<li>
<strong>Array</strong>: 
					An array can be used for local data. There are two supported formats:
					<ul>
						<li>An array of strings: <code>[ "Choice1", "Choice2" ]</code>
</li>
						<li>An array of objects with <code>label</code> and <code>value</code> properties: <code>[ { label: "Choice1", value: "value1" }, ... ]</code>
</li>
					</ul>
					The label property is displayed in the suggestion menu. The value will be inserted into the input element when a user selects an item. If just one property is specified, it will be used for both, e.g., if you provide only <code>value</code> properties, the value will also be used as the label.
				</li>
<li>
<strong>String</strong>: When a string is used, the Autocomplete plugin expects that string to point to a URL resource that will return JSON data. It can be on the same host or on a different one (must provide JSONP). The Autocomplete plugin does not filter the results, instead a query string is added with a <code>term</code> field, which the server-side script should use for filtering the results. For example, if the <code>source</code> option is set to <code>"http://example.com"</code> and the user types <code>foo</code>, a GET request would be made to <code>http://example.com?term=foo</code>. The data itself can be in the same format as the local data described above.</li>
<li>
<strong>Function</strong>: 
					The third variation, a callback, provides the most flexibility and can be used to connect any data source to Autocomplete. The callback gets two arguments:
					<ul>
						<li>A <code>request</code> object, with a single <code>term</code> property, which refers to the value currently in the text input. For example, if the user enters <code>"new yo"</code> in a city field, the Autocomplete term will equal <code>"new yo"</code>.</li>
						<li>A <code>response</code> callback, which expects a single argument: the data to suggest to the user. This data should be filtered based on the provided term, and can be in any of the formats described above for simple local data. It's important when providing a custom source callback to handle errors during the request. You must always call the <code>response</code> callback even if you encounter an error. This ensures that the widget always has the correct state.</li>
					</ul>
					<p>When filtering data locally, you can make use of the built-in <code>$.ui.autocomplete.escapeRegex</code> function. It'll take a single string argument and escape all regex characters, making the result safe to pass to <code>new RegExp()</code>.</p>
				</li>
</ul>
